ABEL H. BARTLETT, OF SPUYTEN DUYVIL, NEW YORK.

IMPROVED REFRIGERATOR.

Specification forming part of Letters Patent No. 37.80], dated March 3, 1863.

To all whom, it may concern:

Be it known that I, ABEL H. BARTLETT, of Spuyten Duyvil, in the county of Westchester and State 01' New York, have invented certain new and useful Improvements in Refrigerators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in WhiCh- Figure l is a perspective view of my improved refrigerator, and Fig. 2 is a front-cutsectional view, the whole front being removed to show the internal arrangement.

Similar letters indicate corresponding parts in the figures.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

C O C, Fig. 2. represent the outer box; D l), inner box; A, lid or top cover; B,ice door;- N N, ice'door frame, made to fit tightly to the ice-box T, so that the evaporation from the melting ice cannot escape into the provisionehambers; E E E E E, space for charcoal or other non-conductor of heat; U U, zinc lining; 1 ice-receptacle; Gr, ice-water reservoir; H and Z, overflow and waste-wattr pipe; I, fancet, arranged with an opening leading from the reservoir G into the pipe H below and Z above, so as to conduct the ice meltings from the reservoir G and from the ice-chamber WV at the same time down through the opening X, and so out at the siphon M, and also when the faucet I is closed from the pipe H an opening in the top conducts the ice-meltings from the chamber W into the reservoir G. This is done to prevent the water flooding the floorandcarpetduringthenight. VVisa-chamher, to be used as required, for either extra ice with the ice-plank Y, as represented in the cuts, or for provisions, with the ice-plank Y removed; J, faucet-opening, leading into the lower angle of the reservoir G, for the purpose of drawing off the water to clean the reservoir; K, trough for catching and conducting off the moisture and impurities which condense on the corrugated metal sides of the ice and ice water box T T, said trough being made lowest in the center so the water will run off the more easily; X X, openings near the center of the trough K, for the escape of the condensed moisture and ice-water; P P, movable partitions of corrugated metal, arranged so as to have two, three, or four provision-chambers, as may be required; R It It R, corrugated metal shelves for the support of provisions; 0 O, provision-chambers, to be reached through doors in front, as shown in Fig. 1; 0, provision-chamber, to be reached by raising the lid A, as shown in Fig. l; T T, metallic ice and ice-water box, corrugated for the purpose of strengthening it and adding to the coin densing-surface.

U U, Fig. 2. is the zinc lining; V, point where the ice-meltings run into the pipe Z; Y, movable ice-shelf covered with zinc. The air circulates as indicated by arrows in Fig.2, first down the cold corrugated sides of the ice and ice-water box T T, wheron it deposits its moisture and impurities, then being capable of absorbing more moisture it passes up, circulating freely through the shelves R R R. R, absorbing the moisture from around the provisions and-comlucting it to the sides of the ice-box, where it condenses. The air then passes down and around again continually.

I claiml. The corrugated metallic ice and water box, constructed and combined with the trough K, the pipes Z and H, the faucetsIand J, or their equivalents, and made and arranged substantially as and for the purpose shown and described.

2. The combination and arrangement of the ice-chambers F and W, the plan k Y, the reservoir G, the pipe Z and H, the faucet I, or their equivalents, whereby the ice-meltings from the chamber W can be either conducted into the reservoir G and retained with the water therein, or the whole allowed to pass off through the faucet I and opening X, substantially as and for the purpose shown and described.

In witness whereof I have hereunto subscribed my name this 21st day of January, 1863.

ABEL H. BARTLETT.
